Lily Tomlin, William Shatner, Cloris Leachman help you plan for retirement and against hippos

On Last Week Tonight, John Oliver got help from such acting legends as Lily Tomlin, William Shatner, Rita Moreno, Fred Willard, and Cloris Leachman to help baby boomers learn about the dangers of getting older.

In a fake public service announcement, the senior celebrities warned the aging baby-boomer population that they’ll need to get their affairs in order soon. Who knows? You may be killed by a hippo tomorrow. Leachman pointed out, “Oh, you think they’re cute. They’re f***ing killing machines.”

Each actor hilariously expounded on the dangers of hippos but then returned to the business of selecting a guardian to make financial and health care decisions. And they all selected the same guardian, “America’s dad,” Tom Hanks. Sadly, Willard would have preferred Jimmy Stewart.

The group ended the piece with a reminder of just how dangerous hippos are and repeated, “F*** hippos.”

Watch a fake royal expert make John Oliver question his own Britishness.
